If you're looking to upgrade your Buick Regal's dashboard without the hassle of cutting it up, this is where it gets exciting. The MHX Series gives you six analog instruments, complete with twin message centers that fit right into the stock housing. For those of you with boosted T-Type cars or Grand Nationals, there's even a BIM expansion module and sender available separately to take things up a notch.

What really sets the MHX Series apart? Well, for starters, those fully lit needles and backlit faces are a game changer. You’ll appreciate the highly visible LCD message centers, especially when you're on the move. And let’s not forget about the tech under the hood—micro-controlled precision stepper motors and solid-state sensors deliver accuracy that you can trust. Plus, the user-customizable display feedback means you can tailor it to your needs. All of this is backed by a limited lifetime warranty, which is pretty much the gold standard for Dakota Digital instrumentation.

Manufactured right in Sioux Falls, South Dakota, the MHX Series is a breath of fresh air in the instrumentation world. For Grand National owners, the Boost gauge is conveniently displayed in the digital readout right beneath the Speedometer or Tachometer, making it easy to keep an eye on performance.

Just a heads up, you’ll need to use your factory bezel since it’s not included, and if you’re running a Grand National ignition system, make sure to grab the SEN-09-7 or a SGI-17 to get that tachometer connection sorted.
